Setting up your Rust project

The Rust package manager, cargo, allows us to create a new project very easily with just one command, cargo new. Let's run it as follow:

  cargo new tetris --bin

You should have a new folder tetris containing the following:

     tetris/
     |
     |- Cargo.toml
     |- src/
         |
         |- main.rs

Note that if you ran cargo new without the --bin flag, then you will have a lib.rs file instead of main.rs.

Now write this into your Cargo.toml file:

    [package]
    name = "tetris"
    version = "0.0.1"

    [dependencies]
    sdl2 = "0.30.0"

Here, we declare that our project's name is tetris, its version is 0.0.1 (it isn't really important at the moment), and that it has a dependency on the sdl2 crate.

For the versioning, Cargo follows SemVer (Semantic Versioning). It works as follows:

[major].[minor].[path]

So here's exactly what every part means:

• Update the [major] number version when you make incompatible API changes
• Update the [minor] number version when adding...
